Chantiers Allais' new range powered by HamiltonJets

French shipyard Chantiers Allais has delivered its first ESUS 190 crew boat 'Anita 1' to Nigerian company Omo-Oria Oil Services.

The new ESUS range is an evolution from Allais' previous SURFER 1000 models, which were designed and built for the French group Bourbon.

Chantiers Allais said they modified the SURFER design in order to be commercially viable with competitors. The ESUS range builds on the SURFER range's success with design modifications that do not alter its fundamental design. Mechanically injected engines, waterjets, a deep-V hull, a fire-fighting pump, air-conditioning and a shock-absorbing accommodation superstructure all remain.

The 19-metre vessel now features 5383 aluminium alloy to lighten the hull and superstructure without compromising its strength, and to reduce corrosion. A bow fender has been adapted for the easy transfer of personnel between the ship and offshore platforms and propulsion is provided by two HJ403 Hamilton waterjets that are powered by two MAN diesel engines rated at 671kW.

The vessel has a cruising speed of 28 knots with a carrying capacity of 25 passengers. During trials at Cherboug by Allais, 'Anita 1' reached a maximum speed of 34 knots while half loaded. The ESUS 190 has a range of 300 nautical miles at cruising speed with a fuel capacity of 3,700 litres. Construction took four months of work at the shipyard.
